Detailed explanation of Incoloy 800H pipe
Incoloy 800H seamless pipes are made from the nickel-iron-chromium alloy Incoloy 800H without any welds in the manufacturing process. The seamless manufacturing process involves extruding a solid billet into a hollow tube. Incoloy 800H seamless pipes have high strength, excellent corrosion resistance and good structural integrity for use in high temperature and corrosive environments. They are commonly used in industries such as chemical processing, power generation and petrochemical.
